Binding ComboBox inside ListView problem
I am attempting to put a bound ComboBox into my ListView. However, I can not get it to bind correctly. All of the textboxes that are in the ListView bind without any issues, but the ComboBox has issues. I am binding to the DefaultView of a DataTable in the code-behind. I have verified that the field that I am trying to bind to exists, as I tested by putting a TextBox in place of the ComboBox when I initially created the ListView. Thanks in advance for any tips.

The following line of code is what does the binding.
-----
child.ItemsSource = customBusinessProcessTables.Tables["process_rule_input_val"].DefaultView;

The following is the listview that I am attempting to bind to.

<ListView Margin ="0,20,0,0" x:Name="_processruleinputvalList" HorizontalAlignment="Left" Width="Auto" Height="120">
<ListView.View>
<GridView>
<GridViewColumn Header="Name" Width="300">
<GridViewColumn.CellTemplate>
<DataTemplate>
<Label Content="{Binding Path=table_and_field}" VerticalContentAlignment="Center"></Label>
